CMake: Fix building libraries on macOS

When building libraries on macOS they'd be missing the SONAME
attribute which causes the linker to embed relative paths into
other libraries and executables:

Dynamic section at offset 0x52794 contains 28 entries:
 Type     Name/Value
(NEEDED) Shared library: [libgcc_s.so]
(NEEDED) Shared library: [Userland/Libraries/LibCrypt/libcrypt.so]
(NEEDED) Shared library: [Userland/Libraries/LibCrypto/libcrypto.so]
(NEEDED) Shared library: [Userland/Libraries/LibC/libc.so]
(NEEDED) Shared library: [libsystem.so]
(NEEDED) Shared library: [libm.so]
(NEEDED) Shared library: [libc.so]

The dynamic linker then fails to load those libraries which makes
the system unbootable.
